SMB3: avoid confusing warning message on mount to Azure
commit ebcd6de987
upstream.
Mounts to Azure cause an unneeded warning message in dmesg
"CIFS: VFS: parse_server_interfaces: incomplete interface info"
Azure rounds up the size (by 8 additional bytes, to a
16 byte boundary) of the structure returned on the query
of the server interfaces at mount time. This is permissible
even though different than other servers so do not log a warning
if query network interfaces response is only rounded up by 8
bytes or fewer.
